QUILTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 456,735, dated July 28, 1891.

Application tiled May 29, 1889.

To LZZ whom, t may concern.'

Be it known that I, LOUIS SCHULTZ, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Quilting-Machines, of which the following is a specification.

This improvement relates to an improvement in quilting-machines for which, on the 22d day of September, 1888, Matthias Koch tiled an application for United States Letters Patent, said application having been numbered Serial No. 286,110.

I will describe such portions of a quiltingmachine as are necessaryto an understanding of my present improvement, and I will then point out the novel features in the claims.

In the accompanying drawings, Figure lis a plan of such portions of the machine which are the Subj ect of the said former application as are necessary to an understanding of the present improvement, together with additional parts which are involved in my present improvement. Fig. 2 is a transverse vertical section. Fig. 3 is a vertical section taken lengthwise of the machine.

Similar letters of reference designate corresponding parts in all the ligures.

A designates the main frame of the machine.

Bzvdesignates the needle-bar. It has secured to it a series of needles I). The needle-bar, in the present instance, has only a vertically-rceiprocating movement, and it may be operated by any suitable means. Shuttle or looping mechanism of any suitable character will be used in conjunction with the needles. As my improvement does not reside in` this mechanism, I do not consider a description necessary.

In this machine the work is supported by two carriages, one of which travels in a straight line to and fro upon the main frame of the machine, and the other of which travels upon the first to and fro in a straight line at right angles to the line of travel of the first.

D designates the lower carriage. Itishere shown as made in two sections. travels along a horizontally-extendin g portion of one of the side pieces of the frame A, and the other section travels along a similar horizontally-extending portion of the other side piece of the frame A. 'Ihis lower carriage D One section Serial No. 312.602. (No model.)

travels to and fro in a direction at right. angies to the length of the needle-bar.

O designates the upper carriage. It is supported by roller dl, j ournaled ou the lower carriage D. I call this carriage O the upper carriage, because it serves to support the fabric. The upper carriage O has a frame composed of two side pieces c2, connected by stretchers or cross-bars c3. The side pieces of this frame have horizontally-extending bar-like portions which travel upon the rollers (Z7. The engagement of these bar-like portions with the rollers (ZT connects the two sections of the carriage D so that they will travel in unison.

The carriage C travels in a direction at right angles to the direction in which the carriage D moves, and therefore the carriage O travels in a direction parallel with the length of the needle-bar.

F designates the fabric to be quilted. It is held by work-holders consisting of pairs of rollers ci' cm arranged near the oppositeends of the carriage C. Rollers I I2 are shown as fitted to this carriage for holding the fabric before and after quilting.

The horizontally-extending portions of the side pieces of the frame A are provided with racks CIS. \Vith these engage gear-wheels d, affixed to a shaft D', which is journaled in the two sections of the carriage D and contributes to connect the two sections so that they will travel in unison. On the shaft D' is atiixed a gear-wheel di", which engages with a reciprocating rack-bar( u. The movements of this rack-bar are caused by two pattern wheels or cams D2 D3, aiiixed to a shaft D4. The pattern-wheel D3 operates in connection with a pin orbowld13 on the rack-bar, and the pattern-Wheel D2 coacts with a pin or bowl (F2 on the rack-bar. On the shaft D4 is afxed a gear-wheel du. Iith this engages a gear-wheeldlf, secured on a shaft D". On this shaft D5 is a worm-wheel (X35. This engages with a continuously-driving worm cl3 on an upright shaft (1.3i, which is j ournaled in a stand or bracket (Zig, secured to the main frame of the machine. This stand or bracket (13S has slots extending at right angles to the axis of the shaft Through these slots pass screws di, which engage with tapped holes in the main frame A. By loosening these screws IOO the stand or bracket may be moved toward and away Ifrom the shaft D5. This makes it possible to use differently-proportioned wormgears and worms iii conjunction with the shafts D5 and CX57. Upon the shaft CX57 is affixed a bevel gear-wheel CX40. It is shown as clamped in place by a screw passing through its hub to impinge upon the shaft. This bevel gear-wheel engages with a bevel gear- Wheel CX41, affixed to a horizontal shaft CX"12 which is journaled in a stand or bracket (X55. This stand or bracket cX5 has in its foot-piece slots extending at right angles to the shaft D5. Screws CXA14 pass through these slots and engage with tapped Yholes in the main frame A. Provision is afforded by this manner of securing the stand or bracket (X45 in place for adjusting it toward and from the shaft D5, and consequently toward and from the shaft CX57. Owing to this the bevel-wheels CX55 CX41 may be removed and bevel-wlieels of different relative proportions may be substituted for effecting a connection between the shaft CX55 and the shaft CX57. The shaft CX45 is rotated by means of a bevel gear-wheel CX45, engaging with a bevel gear-wheel C 55, affixed to said shaft. 'Ihe bevel gear-wheel (X45 is affixed to a horizontal shaft, which extends parallel with the shaft D5 and is supported in a bracket or stand CX45. This bracket or stand CX4G also serves to support the shaft CX55. The shaft, which is furnished with the bevel gear-wheel C55, has also affixed to it a gear-wheel CX57. This engages with a gear-wheel CX45, affixed to the main driving-shaft B5. It will be readily seen that by this train of gearing motion is transmitted from the driving-shaft to .theshaft D5 continuously, or, in other Words, non-intermittingly, and therefore that the pattern- Wheels rotate continuously, and by operating the rack-bar non-intermittingly move the cai'- riage D non-intermittingly whenever the carriage has motion. To make this still more clear, I will say that what I mean is that whenever the carriage D does have motion through this new :mechanism it will not have a stop motion, such as results from a pawl-andratchet movement; but it will have a continnous motion. Manifestly in making some patterns the carriage D may be absolutely at rest during certain intervals; but this will arise from the shape of the pattern-wheels, not from the mechanism which transmits the motion to the patterii-wheels.

I will now briefly describe the mechanism for imparting motion to the upper carriage C. The shaft D5 has affixed to it a bevel gearwheel E10, which meshes with a bevel gear- Wheel E9, affixed to a shaft E7, journaled in a'bracket secured to the main frame of the machine. On the shaft E7 is a gear-wheel E5, which engages with a gear-wheel E5, affixed to a shaft The shaft E5 has affixed to it a pattern-wheel E, which coacts with pins or bowls e5 e4 upon a rack-bar The rack-bar E5 engages with a pinion E5,whicli is secured to a shaft E', and which is made very long in the direction of the axis of the saidsliaft, so that the pinion may move with the shaft lon,- gitudinally and yet remain in gear with the rack-bar.

The shaft E is journaled in one section of the carriage D, and has secured to it collars c e5 beyond the side frames of this section of the carriage, so that the shaft will move longitudinally, corresponding to the carriage D. On the shaft E `gear-wheels E are affixed. These engage with racks r on the horizontally-extending bar-like portions c5 of the carriage C. It will readily be understood that when the shaft D rotates it will, according to the direction of its rotation, move the carriage C horizontally in a direction parallel with the length of the needle-bar.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a quilting-machine, the combination of a series of needles, a carriage movable to and fro upon the main frame of the machine, a second carriage supported upon the first carriage and movable in a direction at right angles to the movement ofthe first carriage, a main driving-shaft, a pattern-wheel for causing the movement of the first carriage, and gearing consisting of a shaft CX57 rotated by the main driving-wheel, a continuouslydriving Worm rotated by said shaft CX57, a shaft D5, and a worin-wheel C 55, engaging with said Worm and rotating` the pattern-wheel, substantially as specified.
